Connectivity and compatibility

The system’s EW-DX EM 2 receiver supports two channels simultaneously, allowing the handheld and bodypack transmitters to operate at the same time without interference. USB ports on the receiver enable charging of spare batteries, reducing downtime between uses. Ethernet connectivity facilitates integration into networked audio setups, providing centralized control and monitoring for complex installations.

Performance and reliability

Designed to withstand the rigors of touring and professional use, the transmitters and receiver feature robust engineering that resists wear from frequent handling and transport. The dynamic MMD 835 capsule offers a cardioid pickup pattern that minimizes feedback on loud stages, while the omnidirectional MKE 2 lavalier captures clear speech in a discreet form factor. Together, they deliver consistent, high-quality audio across a variety of environments.

Ideal uses and environments

This wireless microphone system is well suited to musicians performing live, corporate presenters, educators conducting hybrid classes, and AV professionals managing multi-room events. Its flexibility to switch between handheld and lavalier microphones without changing equipment makes it a strong choice for users who need reliable, professional-grade audio with minimal setup time and easy remote management.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
